How to Become a CNA in Colorado

Becoming a CNA in Colorado requires completing 75 hours of state-approved training and passing the NNAAP competency exam through Credentia, Colorado’s testing vendor. The process takes 4 to 12 weeks and costs $599–$1,200+ for training plus $145 for the exam. Colorado CNAs earn a mean annual wage of $39,050 ($18.77/hr), according to the Bureau of Labor Statistics. For a full pay breakdown by region and setting, see our CNA salary in Colorado guide.

People start CNA certification programs at every stage of life — from recent high school graduates to career changers in their 40s and 50s. Whatever your starting point, this guide covers every step of the Colorado certification process: eligibility, training, the exam, background check, costs, and what comes next.

Whatever brought you here, the certification process is the same. Here’s exactly how it works in Colorado.

Colorado CNA Certification at a Glance

Requirement	Details
Minimum age	18 (or 16 with legal guardian consent)
Training hours	75 minimum (classroom + clinical combined)
Timeline	4–12 weeks
Cost	$599–$1,200+ training; $145 exam

The certification process follows 5 steps:

1. Confirm you meet eligibility requirements
2. Complete a state-approved 75-hour training program
3. Pass the NNAAP competency exam through Credentia
4. Clear the CBI and FBI background check
5. Get listed on the Colorado Nurse Aide Registry through DORA

That’s the quick version. Below, each step is broken down with exact costs, specific exam details, and financial aid options that can cut your out-of-pocket costs significantly.

Meet Basic Eligibility Requirements

Most people who want to become a CNA in Colorado already qualify. Here’s what the state requires.

Age and Education

• Age: 18 years old is the standard minimum. 16-year-olds can enroll with written legal guardian consent — relevant for high school students who want to start early.
• Education: Colorado prefers a high school diploma or GED equivalent, but it’s not universally required at the state level. Some programs accept current high school students. Individual programs may set stricter admission standards than the state minimum, so check directly with your program.
• No prior healthcare experience required. CNA training is designed as an entry point.

Health and Immunization Requirements

Before starting clinical rotations, most programs require:

• A physical exam (within the past year)
• Up-to-date immunizations
• A TB test (tuberculin skin test or QuantiFERON blood test)

These are program-level requirements, not state law, but you’ll encounter them at virtually every approved training site.

Background Check Overview

Colorado requires a fingerprint-based background check for CNA certification. It involves screening through both the Colorado Bureau of Investigation (CBI) and the FBI. Full details are in the Background Check section below. Start thinking about it early in the process.

Colorado also requires demonstration of legal U.S. presence for CNA certification. You’ll need a valid Social Security number or Individual Taxpayer Identification Number to complete the registry process.

Once you’ve confirmed eligibility, the next step is finding a state-approved training program.

Complete a State-Approved Training Program

Colorado requires a minimum of 75 hours of combined classroom and clinical training through a state-approved program. That’s the floor — many programs run 80 to 120 hours.

What Training Covers (75-Hour Minimum)

Training covers the core skills every CNA needs: infection control, resident rights, vital signs measurement, personal care procedures, patient safety, and communication with the care team. You’ll spend the first portion in a classroom or lab setting, then move to supervised clinical hours at a care facility.

Clinical hours must be completed in person at an approved site. There’s no fully online path to CNA certification in Colorado — the hands-on component is non-negotiable.

Program Format Options

Colorado allows two main formats:

Format	Structure	Best For
Traditional in-person	All classroom and clinical hours in person	Learners who prefer a structured daily schedule
Hybrid	40 hours online theory + 28 hours in-person lab + 16 hours supervised clinical	Working adults who need scheduling flexibility

The hybrid format is offered by some Colorado programs. The 40+28+16 breakdown means you can complete theory at your own pace before showing up for lab and clinical work. For more context on how hybrid programs work, see our guide on online CNA classes.

The excitement that comes with committing to this step is real. As one Reddit user shared before starting their program:

“My New CNA starter pack! Excited to be starting classes soon!”
— r/cna, 524 upvotes

That energy carries you through. Colorado’s approved programs give you a clear, structured path to certification.

Finding an Approved Program

When evaluating programs, check three things:

1. NATCEP approval — Colorado’s state-approved training and competency evaluation programs carry this designation. If a program isn’t NATCEP-approved, you won’t be eligible to sit for the state exam.
2. Exam pass rates — Ask programs directly. Higher pass rates signal better clinical preparation.
3. Clinical site quality — Where you complete your clinical hours matters for how ready you feel on test day.

For a directory of approved Colorado CNA programs by location, see our Colorado CNA programs page. Not sure how to evaluate programs against each other? Our guide on how to choose a CNA program walks through what actually matters.

Colorado also offers a Parent CNA pathway for parents who want to provide certified care to their own medically eligible children at home — covered in detail in the Parent CNA section below.

Training is your biggest upfront cost. The next section breaks down exactly what you’ll pay and how to reduce it.

Pass the Colorado CNA Competency Exam

Colorado uses Credentia for its NNAAP competency exam, administered through the CNA365 platform. This is different from most states, which use Prometric. If someone tells you to register through Prometric, that's wrong for Colorado.

Written Exam

The written portion consists of 70 multiple-choice questions: 60 content questions covering nursing aide knowledge, and 10 reading comprehension questions. You have 2 hours to complete it.

If you have difficulty reading English, you can request an oral version when you register. The oral exam replaces the 70-question written test with 160 audio questions. You must select this option at registration -- you can't switch formats on test day.

For a broader overview of the NNAAP format used across states, see our CNA exam guide.

Skills Evaluation

In the skills portion, you perform 5 randomly selected nursing tasks in front of a trained evaluator. You have 25 minutes to complete all 5 tasks. Examples of skills that may be selected: handwashing technique, measuring vital signs, patient positioning, bed-making, and passive range of motion exercises.

The evaluator grades you on each step of each task, including technique details like handwashing before and after patient contact. Thoroughness matters more than speed.

The skills portion makes most test-takers nervous. The relief of passing is real:

"just wanted to say i've officially passed all the tests and i am a registered cna"
-- r/cna, 671 upvotes

With structured preparation and your training program behind you, you're walking into that exam with the skills you need. Candidates who feel most confident on test day are those who practiced skills on real classmates during open lab hours, not just on mannequins.

Online Remote Proctoring Option

Colorado offers online remote proctoring for the written exam through the CNA365 platform. You can take the written portion from home with a webcam and proctored session instead of traveling to a Regional Test Site. The skills evaluation must still be done in person at a Regional Test Site. That portion cannot be done remotely.

What to Bring on Exam Day

• Government-issued photo ID (must match your Credentia registration name exactly)
• Confirmation email or registration number
• For skills evaluation: scrubs or clinical attire, watch with a second hand (no smartwatches)
• Arrive 30 minutes early -- late arrivals may be turned away and forfeit the attempt fee

Colorado tests from a pool of 23 possible skills. You'll perform 5 on exam day. Download the official Credentia Colorado Candidate Handbook to see the exact checklist for every skill, including the critical-element steps you cannot miss.

Colorado Regional Test Sites are listed on your Credentia registration confirmation. Verify current site locations on Credentia's website.

Retake Policy

You get 3 attempts per component within 24 months of your initial application. The written exam and skills evaluation are tracked separately -- if you fail the skills portion but pass the written, you only retake skills. You don't lose your written pass.

After 3 failed attempts on either component, you must complete a new state-approved training program before testing again. There's no mandatory waiting period between attempts, so you can reschedule immediately after a failed attempt.

One practical note on skills preparation, from someone who's been through it:

"Don't skip the practice skills sessions. The exam evaluators grade you on every single step, including hand washing technique. It's more strict than you'd expect."
-- r/cna

That's consistent with how Credentia designs the evaluation. If your program offers open lab hours, use them.

If you don't pass the first time, our CNA exam retake guide covers what to do next, including how to adjust your preparation strategy.

Exam Fees

Component	Fee
Written exam	$50
Skills evaluation	$95
Combined (both)	$145

You pay per attempt. If you retake only the skills portion, you pay $95, not the combined $145.

How to Register

Register through Credentia at credentia.com/test-takers/co or through the CNA365 platform. You'll select your test date, choose in-person or remote proctoring for the written exam, and pay the fee online.

Before your test date, work through our free CNA practice exam to get familiar with the question format. Drilling key concepts with CNA exam flash cards helps reinforce what you learned in class, especially for the 60 content questions. For a structured study approach, our guide on study strategies for the CNA exam covers what works and what doesn't.

Once you've passed both parts of the exam, one step remains before you're on the Colorado Nurse Aide Registry: the background check.

Background Check and Registry Listing

CBI and FBI Fingerprinting

Colorado requires fingerprint-based screening through both the Colorado Bureau of Investigation (CBI) at the state level and the FBI at the federal level. This dual-agency check is more thorough than a basic name search or single-agency check.

Colorado uses approved vendors -- IdentoGO and Colorado Fingerprinting -- for CABS (Colorado Applicant Background Services) fingerprinting. You'll need the specific service code provided by your training program or DORA to ensure results route to the Board of Nursing. You cannot use a generic police station fingerprinting service.

Processing typically takes 2--4 weeks from fingerprinting to DORA clearance, though times vary during high-volume periods. Plan accordingly if you have a job start date waiting on your registry listing.

Disqualifying Offenses

DORA reviews backgrounds for these categories of offenses:

• Recent felony convictions
• Crimes involving violence or abuse
• Drug offenses
• Child abuse or neglect
• Unlawful sexual behavior

Two things matter here. First, "disqualifying" doesn't mean automatic permanent denial. DORA's review considers the nature of the offense and how much time has elapsed since conviction. Second, the review is conducted by DORA, not by a third-party algorithm. You have the opportunity to provide context.

If you have questions about a specific situation, contact DORA directly.

Checking Your Registry Status

After passing the exam and clearing the background check, you're listed on the Colorado Nurse Aide Registry through DORA. You can verify your certification status, expiration date, and registry listing through the DORA online portal.

For a step-by-step walkthrough of the verification process, see our Colorado CNA license lookup guide.

With the certification process clear, the question most people ask next: what does all of this actually cost?

How Much Does CNA Training Cost in Colorado?

Before listing tuition, here's the number that actually matters: total out-of-pocket cost runs approximately $800--$1,500+ without financial aid. Training programs advertise the tuition. They don't always mention what comes with it.

Tip: Ask your program upfront whether textbooks, scrubs, and CPR certification are included in tuition or billed separately. The "hidden costs" below can add $175--$425 to your total.

Tuition and Exam Fees

Cost Item	Range
Training tuition	$599--$1,200+
Written exam	$50
Skills evaluation	$95
Total (tuition + exam)	$744--$1,345+

For a concrete reference point: Arapahoe Community College's nurse aide program runs approximately $1,200 for the 6-credit program. It's COF-eligible, meaning Colorado residents can use the College Opportunity Fund to offset tuition costs.

Additional Costs Most Programs Don't Mention

Item	Estimated Cost
Textbooks	$30--$80
Uniforms/scrubs	$25--$60
CPR/First Aid certification	$30--$60
Vaccinations + TB test	$50--$150 (varies by insurance)
CBI + FBI fingerprinting	$40--$75
Additional cost subtotal	$175--$425

Add those to the tuition and exam fees, and the realistic range is $920--$1,770+ before any financial aid.

Financial Aid and Free Training Options

Three paths can reduce your cost significantly -- or eliminate it entirely.

WIOA funding through Colorado Workforce Centers
The Workforce Innovation and Opportunity Act funds training for eligible workers. Colorado Workforce Centers can cover tuition, textbooks, exam fees, and sometimes childcare and transportation. To find out if you qualify, contact your local Colorado Workforce Center. Ask specifically about CNA training funding and what documentation they need.

Employer-sponsored training
Some home health agencies and nursing facilities in Colorado cover full tuition in exchange for a work commitment of 6 months to a year after certification. Ask at facilities near you before paying out of pocket. This option combines CNA certification directly with job placement.

College Opportunity Fund (COF) at community colleges
If you attend a community college like Arapahoe CC, you're eligible for COF, Colorado's state tuition subsidy for residents. This brings community college tuition down meaningfully.

If you want free CNA training in Colorado, WIOA and employer sponsorship are the most reliable paths. Scholarships and community grants exist through local nonprofits and healthcare organizations, but availability varies.

To put these costs in context, Colorado CNAs earn a mean annual wage of $39,050, according to the Bureau of Labor Statistics. For a full breakdown of pay by region and facility type, see our CNA salary in Colorado guide.

Colorado's Parent CNA Program

Colorado offers a Parent CNA program that's not available in most states. It lets parents become certified nursing aides to provide personal care services to their own children with disabilities or medical needs -- at home, through Health First Colorado (Colorado's Medicaid program).

What It Is

If you're a parent or legal guardian of a child enrolled in Health First Colorado who requires help with daily living activities, you may be eligible to train as a CNA specifically to care for that child. Once certified, you can receive Medicaid compensation for the care you provide. Both parents in a household can apply separately.

This program operates through Home and Community Based Services (HCBS) waivers -- funding that supports care for people with disabilities in home settings rather than institutions.

How It Differs from Standard CNA Certification

The training pathway is identical: you complete a 75-hour state-approved program and pass the same NNAAP exam through Credentia. The difference is the employment context. After certification, your "employer" is the HCBS waiver system, and you're providing care to your own child rather than working at a facility.

Parents may receive Medicaid compensation for this care. That's a meaningful financial consideration that doesn't get mentioned in most CNA resources.

Financial Aid for Parent CNAs

Health First Colorado may cover the cost of training for Parent CNA candidates. This makes the Parent CNA program one of the lower-barrier paths to CNA certification in Colorado.

To explore eligibility, contact Health First Colorado or your local Colorado Workforce Center. Ask specifically about training funding for the Parent CNA program through HCBS.

Parent CNAs follow the same 24-month renewal cycle but may need to provide evidence of continuing education at renewal time.

Transferring Your CNA to Colorado (Reciprocity)

If you're already certified in another state and moving to Colorado, you don't retake the exam. Colorado accepts reciprocity for active, unencumbered out-of-state certifications.

"Unencumbered" means no disciplinary actions, suspensions, or restrictions are attached to your current certification. If your certification is in good standing in your home state, you're eligible to transfer.

Eligibility and Application

To apply for reciprocity:

1. Confirm your out-of-state CNA certification is active with no disciplinary history
2. Submit an application through the DORA Online Services Portal -- select "Nurse Aide" and choose the reciprocity/endorsement application. Before DORA issues your certification, you must also complete your Healthcare Professions Profile (HPPP), a separate state-mandated disclosure step. Your certification will show as "Pending" until this profile is finished.
3. Pay the required fee (Colorado is not a free reciprocity state -- check the DORA portal for current amounts)

Colorado uses Credentia for its NNAAP exam, but your home state may use a different vendor. Our NNAAP exam vendors by state guide explains vendor differences if you're coming from a Prometric state.

Fees and the 4-Month Employer Window

Colorado employers can hire you while your reciprocity application is processing. You don't have to wait for paperwork to clear before starting work. But you must complete the Colorado certification process within 4 months of your hire date.

This matters if you've just moved to Colorado and need income immediately. Start working, submit your application, and get fully certified within the 4-month window.

Reciprocity applicants may still need a background check, though fingerprinting requirements may be waived in some cases. Confirm with DORA during your application.

Whether you're newly certified or transferring from another state, CNA certification is often the starting point for a longer healthcare career.

Career Advancement from CNA in Colorado

CNA work is your starting point, not your ceiling. Colorado has clear pathways for CNAs who want to advance.

CNA-to-LPN and CNA-to-RN Pathways

Colorado community colleges offer CNA-to-LPN bridge programs designed specifically for working certified nursing aides. These programs give credit for CNA experience, shorten the LPN path, and often prioritize candidates with patient care hours. Your CNA certification isn't just a resume line -- it's a prerequisite advantage.

For the CNA-to-RN pathway, CNA experience strengthens applications to ADN (Associate Degree in Nursing) programs at Colorado community colleges. Most ADN programs value clinical hours in their admissions review, and CNA work provides exactly that.

Many people pursue CNA certification with nursing school in mind. That's a legitimate and common path:

"Genuinely, for those who don't like being a CNA, I see some of you guys want to be a nurse instead"
-- r/cna, 355 upvotes

CNA experience doesn't just build clinical skills. It gives you patient-facing hours that nursing programs value in admissions. Many Colorado community college ADN programs specifically look for CNA experience.

Specializations and Settings

"CNA" isn't one job. The credential opens multiple settings with meaningfully different working conditions:

• Hospitals (UCHealth, SCL Health, Children's Colorado): higher pay, faster pace
• Home health agencies: flexible scheduling, one-on-one patient relationships
• Hospice: specialized emotional and physical care, smaller caseloads
• Long-term care: steady hours, established patient relationships
• Rehabilitation facilities: goal-oriented care with patient improvement arc

CNA work is physically and emotionally demanding. The community is honest about that:

"I wonder how many CNAs quit after this"
-- r/cna, 4,223 upvotes

That honesty is exactly why career planning matters. Knowing your options and having a plan is what separates CNAs who burn out from those who build careers.

Your earning potential varies significantly by setting and experience level. For a complete breakdown of pay by Colorado region and facility type, see our CNA salary in Colorado guide.
